Overview#
Lower back pain (LBP) is the leading cause of disability worldwide and in India, affecting approximately 60 % of adults at some point in their lives. It is especially common in people with desk jobs, those who perform heavy manual labour, and women during and after pregnancy. In most cases (about 90 %), lower back pain is "non-specific" — meaning it is not caused by a serious underlying condition — and improves within 4–6 weeks with appropriate self-care.
However, certain types of back pain can indicate disc problems, nerve compression, or, rarely, more serious conditions like spinal infections or fractures.
Common Causes#
- Muscular strain or sprain — the most common cause, often due to poor lifting technique, sudden movements, or prolonged sitting.
- Poor posture — slouching at a desk or using a phone for hours causes chronic strain on lumbar muscles and ligaments.
- Lumbar disc herniation (slipped disc) — the gel-like centre of a spinal disc bulges out and presses on a nerve, causing pain radiating to the leg (sciatica).
- Degenerative disc disease — age-related wear and tear of spinal discs, more common after age 40.
- Spondylosis — osteoarthritis of the spine, very common in older Indians.
- Vitamin D deficiency — widespread in India and linked to diffuse musculoskeletal pain including the back.
- Kidney stones or UTI — pain in the flank or lower back that may be confused with musculoskeletal pain.
Associated Symptoms#
Lower back pain may be accompanied by stiffness (especially in the morning), radiating pain to the buttock or leg (sciatica), muscle spasms, difficulty bending or standing, and in severe cases, numbness or weakness in the legs.
Home Remedies & Self-Care#
- Stay active — prolonged bed rest is counterproductive. Gentle movement and walking aid recovery.
- Practise core-strengthening exercises: cat-cow stretches, pelvic tilts, and bridges.
- Use a firm mattress and sleep on your side with a pillow between the knees.
- Apply heat packs to the affected area for 15–20 minutes to relax muscles.
- Maintain good posture — use an ergonomic chair; keep the screen at eye level.
- Avoid lifting heavy objects; if you must, bend at the knees, not the waist.
When It's Serious#
Seek urgent medical attention if back pain is accompanied by:
- Loss of bladder or bowel control (possible cauda equina syndrome — a surgical emergency).
- Progressive weakness or numbness in both legs.
- Severe pain after a fall or trauma.
- Unexplained weight loss with persistent back pain (possible malignancy).
- Fever with back pain (possible spinal infection).
- Pain that wakes you from sleep consistently.
Diagnosis & Tests#
Your doctor may recommend:
- X-ray of the lumbar spine — to check for fractures, spondylosis, or alignment issues.
- MRI of the lumbar spine — the gold standard for evaluating disc herniation and nerve compression.
- Vitamin D (25-OH) — to check for deficiency contributing to pain.
- Serum calcium — especially in postmenopausal women with suspected osteoporosis.
- Urine routine — to rule out kidney stones or infection.
- ESR / CRP — if infection or inflammatory cause is suspected.
When to See a Doctor#
Consult a doctor if back pain persists beyond 4–6 weeks, radiates to the legs, or is accompanied by any red-flag symptoms. Most cases respond well to physiotherapy and lifestyle changes, but timely evaluation ensures serious causes are not missed.
